The impact of radial migration on disk galaxy star formation histories: II. Role of bar strength, disk thickness, and merger history

J. P. Bernaldez, I. Minchev, B. Ratcliffe +7

Reconstructing the star formation history (SFH) of disk galaxies is central to understanding their growth and evolution, yet such estimates can be strongly biased by stellar radial…

Milky Way disc & Bulge in situ populations: ESO white paper - Expanding horizons call

M. Bergemann, G. Kordopatis, G. Casali +11

The formation and evolution of the Milky Way's disc, bar, and bulge remain fundamentally limited by the lack of a contiguous, Galaxy-wide, high-precision chemo-dynamical map. Key o…

The impact of radial migration on disk galaxy star formation histories I. Biases in spatially resolved estimates

I. Minchev, K. Attard, B. Ratcliffe +9

Knowledge of the spatially resolved star formation history (SFH) of disk galaxies provides crucial insight into disk assembly, quenching, and chemical evolution. However, most reco…

Rediscovering the Milky Way with an orbit superposition approach and APOGEE data V. The disc growth and history of star formation

Bridget Ratcliffe, Sergey Khoperskov, Nathan Lee +8

The Milky Way's (MW's) star formation history (SFH) offers insight into the chronology of its assembly and the mechanisms driving its structural development. In this study, we pres…

On inertial forces (indirect terms) in problems with a central body

Aurélien Crida, Clément Baruteau, Philippine Griveaud +14

Gravitational systems in astrophysics often comprise a body -- the primary -- that far outweights the others, and which is taken as the centre of the reference frame. A fictitious…

Bar-spiral interaction produces radial migration and star formation bursts

Léa Marques, Ivan Minchev, Bridget Ratcliffe +8

Central bars and spirals are known to strongly impact the evolution of their host galaxies, both in terms of dynamics and star formation. Their typically different pattern speeds c…
